Description

Technical Field

[0001] This invention relates to the field of tunnel waterproofing and drainage technology, specifically a waterproofing and drainage device and method for high-pressure water tunnels. Background Technology

[0002] Due to crustal movement and rock weathering, mountain fractures have developed, and rocks have broken into fracture zones of varying sizes. Some of these fracture zones are tens of meters wide and extend across the surface. Supplies from atmospheric precipitation and surface runoff can result in water head heights reaching hundreds of meters. When tunnels pass through these fracture zones, the tunnel lining will bear enormous water pressure from above, severely impacting project safety. In such cases, drainage is necessary to reduce the water pressure.

[0003] In existing technology, transverse drainage channels are buried in the arc-shaped top wall of the tunnel, and longitudinal drainage channels are opened in the foundation of the tunnel. The transverse drainage channels are used to receive the water seeping from the soil and rock above the tunnel and collect the water into the longitudinal drainage channels. Then, the water in the longitudinal drainage channels is discharged through drainage facilities. Geotextile is then laid on the inner wall of the tunnel, followed by the construction of waterstops and waterproof membranes, and then the secondary lining is constructed.

[0004] However, the silt and sand in the water seeping from the rocks can easily adhere to the inner wall of the drainage pipes, causing blockages in the transverse drainage channels. Once a blockage occurs, it is necessary to locate and clear the blocked transverse drainage channels in time; otherwise, the water in the tunnel will not drain properly, reducing the tunnel's drainage capacity and causing water seepage, which will have a very adverse impact on driving safety. However, in existing tunnel drainage systems, the transverse drainage channels are all fixedly buried inside the tunnel lining, making it difficult for workers to clear the transverse drainage channels.

[0005] Therefore, the present invention provides a drainage device and method for high-pressure water tunnels to solve the above problems. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides a high-pressure water tunnel drainage device and method, which effectively solves the problem that blockage of drainage channels leads to poor drainage of water in the tunnel, resulting in reduced drainage capacity of the tunnel and subsequent water seepage, which has a very serious adverse impact on traffic safety; and the problem that it is difficult to dredge the transverse drainage channels.

[0007] A high-pressure water-bearing tunnel drainage device includes a tunnel lining fixedly installed on the tunnel foundation. A guy box is fixedly installed on the top of the inner side of the tunnel lining. Drainage pipes are fixedly installed on the inner sides of the tunnel lining on both sides of the guy box. Two symmetrical drainage ditches are opened on the top surface of the tunnel foundation on the inner side of the tunnel lining. The bottom ends of the two drainage pipes are fixedly connected to outlet pipes located in the drainage ditches. Multiple "V"-shaped drainage grooves are opened on the outer side of the tunnel lining. The tip of each drainage groove penetrates the tunnel lining and is fixedly installed. There are drainage pipes, and the other end of each drainage pipe is connected to a drain pipe. A water pipe box is installed inside the tunnel foundation. Drive pipes located inside the tunnel foundation are fixedly connected to the left and right sides of the water pipe box. The other ends of the two drive pipes are fixedly connected to the bottom end of the drain pipe located on the same side. A sealing plate located below the water outlet pipe is fixedly installed inside the bottom end of each of the two drain pipes. A cleaning groove is opened on the inner side of the drain pipe. A cleaning scraper is slidably installed inside each drain pipe. A sealing scraper is rotatably connected to the side of the cleaning scraper away from the pull box. The cleaning scraper includes a cleaning rod, on the outer surface of which two axially symmetrical fan-shaped cleaning plates are fixedly installed. A cleaning slider located inside a cleaning groove is fixedly installed on the outer surface of one of the fan-shaped cleaning plates. The sealing scraper includes a sealing rod rotatably connected to the cleaning rod. Two axially symmetrical fan-shaped sealing plates are fixedly installed on the outer surface of the sealing rod. A pull wire connects the two cleaning rods to the pull wire box. A braided water pipe is fixedly connected to the end of each sealing rod away from the pull wire box. The other end of each braided water pipe passes through the sealing plate and through the drive pipe to connect to the water pipe box. A spray hole is opened at the end of each braided water pipe near the sealing rod. The cable box is equipped with a cable pulling device, the water pipe box is equipped with a water pipe winding device, and each drain pipe has a rotating device located below the sealing plate and connected to the braided water pipe rotatably installed inside its bottom end.

[0008] Preferably, the wire pulling device includes two wire pulling shafts rotatably mounted inside a wire pulling box. The two wires are respectively fixed and wound on the corresponding wire pulling shafts. Both wire pulling shafts are connected to wire pulling shaft gears, and the two wire pulling shaft gears mesh with each other. A wire pulling motor connected to one of the wire pulling shafts is fixedly installed inside the wire pulling box.

[0009] Preferably, the water pipe winding device includes a water pipe winding shaft rotatably installed inside a water pipe box, one end of each of the two braided water pipes is wound on the water pipe winding shaft, a winding motor connected to the water pipe winding shaft is fixedly installed inside the water pipe box, a water pump is installed inside the water pipe box, and both of the braided water pipes are connected to the water pump.

[0010] Preferably, the rotating device includes a rotating bevel gear coaxially mounted inside the drain pipe and coaxially surrounding the outside of the braided water pipe. Two limiting wheels located on both sides of the braided water pipe are rotatably mounted on the inner side of the rotating bevel gear. The axes of the two limiting wheels are perpendicular to the axis of the rotating bevel gear. Spikes are fixedly mounted on the outer surfaces of the two limiting wheels. A driving bevel gear that meshes with the rotating bevel gear is rotatably mounted on the inner side of the drain pipe. A rotating motor connected to the driving bevel gear is fixedly mounted on the outer side of the drain pipe.

[0011] Preferably, each of the two fan-shaped cleaning plates has an arc-shaped limiting groove on the side away from the pull wire box, and each of the two fan-shaped sealing plates has a limiting block fixedly installed in the two arc-shaped limiting grooves on the side near the pull wire box.

[0012] Preferably, the braided water pipe is a stainless steel braided water pipe, and its outer layer is a stainless steel wire braided layer.

[0013] A method for using a drainage and waterproofing device for high-pressure water tunnels is as follows: a. During drainage: Groundwater on the outside of the tunnel lining flows into the drainage channel, then flows into the drainage pipe through the drainage pipe, and is discharged into the drainage ditch from the outlet pipe; b. During cleaning: First, the rotating motor drives the rotating helical gear to rotate, which in turn drives the braided water pipe to rotate through two limiting wheels with spikes. The braided water pipe drives the sealing rod to rotate, and the sealing rod drives the two fan-shaped sealing plates to move circumferentially to the space between the two fan-shaped cleaning plates, so that the two fan-shaped cleaning plates and the two fan-shaped sealing plates form a complete circular cleaning plate that is sealed and fits tightly against the inner wall of the drain pipe. c. Then, start the wire pulling motor and the winding motor at the same time. The winding motor starts and drives the water pipe winding shaft to rotate, and begins to wind the two braided water pipes. When the braided water pipes pass through the rotating helical gears axially, they can drive the two limiting wheels to rotate. At the same time, the wire pulling motor starts and drives the two wire pulling shafts to release the two wires. The two braided water pipes can pull the two circular cleaning plates to move along the drain pipe, thereby scraping off the mud and sand on the inner wall of the drain pipe for cleaning. At the same time, the braided water pipes are supplied with water by the water pump and clean the inner wall of the drain pipe through the spray nozzles. d. Upon completion of cleaning: First, start the rotary motor in reverse, causing the braided water pipe and sealing rod to rotate in the opposite direction. The two sector-shaped sealing plates rotate in the opposite direction to return to the state of overlapping with the two sector-shaped cleaning plates. Then, start the pull wire motor and winding motor in reverse at the same time, causing the two pull wire shafts to rotate and wind the two pull wires. Meanwhile, the water pipe winding shaft releases the two braided water pipes. As the two pull wires are gradually wound, they can pull the top of the drain pipe of the two cleaning rod boxes to move and reset.

[0014] Compared with existing technologies, this invention can wind a braided water pipe by rotating a water pipe winding shaft, thereby pulling a circular cleaning plate formed by two fan-shaped cleaning plates and two fan-shaped sealing plates to move along the length of the drain pipe inside, thus scraping away mud and sand inside the drain pipe. The braided water pipe can also perform high-pressure flushing of the inner wall of the drain pipe, preventing the drain pipe from becoming clogged with mud and sand over long-term use. The rotating helical gear, through two limiting wheels with protrusions, can drive the braided water pipe to rotate, thereby realizing the mutual rotation between the two fan-shaped cleaning plates and the two fan-shaped sealing plates. When the drain pipe is not being cleaned, water can flow through the space between the two fan-shaped cleaning plates and the two fan-shaped sealing plates, achieving normal drainage function.

[0022] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 7 The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0023] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0024] Example 1: This invention relates to a high-pressure water tunnel drainage device, comprising a tunnel lining 1 fixedly installed on a tunnel foundation 01. A cable box 2 is fixedly installed on the top of the inner side of the tunnel lining 1. Drainage pipes 3 are fixedly installed on the inner sides of the tunnel lining 1 on both sides of the cable box 2. The outer sides of the drainage pipes 3 are attached to the inner sides of the tunnel lining 1, and the bottom ends of both drainage pipes 3 are buried inside the tunnel foundation 01. Two symmetrical drainage ditches 02 are opened on the top surface of the tunnel foundation 01 on the inner side of the tunnel lining 1 for drainage. Ditch 02 extends along the length of the tunnel. The bottom ends of the two drainage pipes 3 are fixedly connected to outlet pipes 03, the other end of which is located within the drainage ditch 02. The two outlet pipes 03 are located above the tunnel foundation 01. Water in the drainage pipes 3 is discharged into the drainage ditch 02 through the outlet pipes 03. Multiple "V"-shaped drainage channels 4 are formed on the outer surface of the tunnel lining 1. The tip of each drainage channel 4 penetrates the tunnel lining 1 and is fixedly fitted with a drainage pipe 5. The other end of each drainage pipe 5 is connected to the drainage pipe 3. Natural water on the outside of the tunnel lining 1 can... The water flows through the drainage channel 4 to the inlet of the drainage pipe 5, and then through the drainage pipe 5 into the drainage pipe 3, finally entering the drainage ditch 02. A water pipe box 6 is installed inside the tunnel foundation 01. Drive pipes 7 located inside the tunnel foundation 01 are fixedly connected to the left and right sides of the water pipe box 6, respectively. The other ends of the two drive pipes 7 are fixedly connected to the bottom end of the drainage pipe 3 located on the same side, so that each drive pipe 7 is connected to the interior of the corresponding drainage pipe 3. A sealing device located below the outlet pipe 03 is fixedly installed inside the bottom end of each of the two drainage pipes 3. The sealing plate 04 can isolate the drain pipe 3, so that when the water flows to the sealing plate 04, it will flow from the outlet pipe 03 into the drain ditch 02, instead of flowing into the drive pipe 7. The inner side of the drain pipe 3 has a cleaning groove 8 along its length. A cleaning scraper 9 is slidably installed inside each drain pipe 3. A sealing scraper 10 is rotatably connected to the side of the cleaning scraper 9 away from the pull box 2. The cleaning scraper 9 and the sealing scraper 10 can move along the length of the drain pipe 3 and can clean the mud and sand on the inner wall of the drain pipe 3. The cleaning scraper 9 includes a cleaning rod 901. Two axially symmetrical sector-shaped cleaning plates 902 are fixedly installed on the outer surface of the cleaning rod 901. A cleaning slider 903 located inside the cleaning groove 8 is fixedly installed on the outer surface of one of the sector-shaped cleaning plates 902. The cleaning scraper 9 can move along its length inside the drain pipe 3 through the cooperation of the cleaning slider 903 and the cleaning groove 8. The sealing scraper 10 includes a sealing rod 101 rotatably connected to the cleaning rod 901. Two axially symmetrical sector-shaped sealing plates 102 are fixedly installed on the outer surface of the sealing rod 101. When the two sector-shaped sealing plates 102 coincide with the two sector-shaped cleaning plates 902, the water flow can pass normally through the drain pipe 3. Inside, when it is necessary to clean the inner wall of the drain pipe 3, the sealing cover 101 can be rotated, so that the two fan-shaped sealing plates 102 can be rotated to the space between the two fan-shaped cleaning plates 902, so that the two fan-shaped cleaning plates 902 and the two fan-shaped sealing plates 102 form a complete circular cleaning plate. When the circular cleaning plate moves along the length of the drain pipe 3, the inner wall of the drain pipe 3 can be thoroughly cleaned. Sealing strips are installed on the side of the two fan-shaped cleaning plates 902 and the two fan-shaped sealing plates 102 that are in contact with the drain pipe 3, so that all four can make soft contact with the inner wall of the drain pipe 3 and can move closely against the inner wall of the drain pipe 3, thereby scraping off the mud and sand on the inner wall of the drain pipe 3. A pull wire 11 connects the two cleaning rods 901 to the pull box 2. The pull box 2 can pull the two cleaning rods 901 towards the top of the two drain pipes 3 via the pull wire 11, thereby moving the two fan-shaped cleaning plates 902 and the two fan-shaped sealing plates 102 towards the top of the drain pipes 3. A braided water pipe 12 is fixedly connected to the end of each sealing rod 101 away from the pull box 2. When the braided water pipe 12 rotates, it can drive the sealing cover 101 to rotate. The braided water pipe 12 itself is elastic, flexible, and can be wound, but its outer surface has a braided layer, making it less prone to axial twisting. Therefore, rotating the braided water pipe 12 can drive the sealing rod 101 to rotate, thereby achieving a seal between the two fan-shaped cleaning plates 902 and the two fan-shaped sealing plates 102. The other end of each braided water pipe 12 passes through the sealing plate 04 and... The drive pipe 7 is connected to the water pipe box 6. The sealing plate 04 has a through hole in the middle. A sealing ring is installed on the inner side of the through hole to seal against the outer side of the braided water pipe 12, so that the braided water pipe 12 and the sealing plate 04 are sealed together. The braided water pipe 12 can move axially from the middle of the sealing plate 04 and can also rotate in the middle of the sealing plate 04. The water pipe box 6 can pull the two braided water pipes 12, thereby driving the two sealing rods 101 to move towards the bottom of the two drain pipes 3, thereby driving the two circular cleaning plates to move towards the bottom of the drain pipes 3 for cleaning. Each braided water pipe 12 has a spray hole 13 at one end near the sealing rod 101. The braided water pipe 12 is connected to a water source. When it drives the circular cleaning plates to move, it can perform high-pressure flushing on the inner wall of the drain pipe 3 through the spray hole 13, which is convenient for scraping off mud and sand. The pull box 2 is equipped with a pull device that can pull and wind the two pull wires 11. The water pipe box 6 is equipped with a water pipe winding device that can pull and wind the two braided water pipes 12. When the pull device pulls and winds the two pull wires 11, the water pipe winding device releases the two braided water pipes 12. Similarly, when the water pipe winding device pulls and winds the two braided water pipes 12, the pull device releases the two pull wires 11. Each drain pipe 3 has a rotating device rotatably installed inside its bottom end, located below the sealing plate 04 and connected to the braided water pipe 12. The rotating device can drive the braided water pipe 12 to rotate, thereby realizing the rotation of the two fan-shaped sealing plates 102 and forming a circular cleaning plate at the front of the drain pipe 3.

[0025] In Embodiment 2, based on Embodiment 1, the pull-wire device includes two pull-wire shafts 14 rotatably mounted inside the pull-wire box 2. Two pull wires 11 are respectively fixed and wound around the corresponding pull-wire shafts 14. Each pull-wire shaft 14 is connected to a pull-wire shaft gear 15, and the two pull-wire shaft gears 15 mesh with each other. Through the meshing of the two pull-wire shaft gears 15, the two pull-wire shafts 14 can rotate synchronously. When the two pull-wire shafts 14 rotate synchronously, they can simultaneously wind or release the two pull wires 11, thereby driving the circular cleaning plate to move towards the top of the drain pipe 3. A pull-wire motor 16, connected to one of the pull-wire shafts 14, is fixedly installed inside the pull-wire box 2. The pull-wire motor 16 is connected to a power supply and a controller. The pull-wire motor 16 can drive one of the pull-wire shafts 14 to rotate, thereby causing the two pull-wire shafts 14 to rotate synchronously.

[0026] In Example 3, based on Example 2, the water pipe winding device includes a water pipe winding shaft 17 rotatably installed inside a water pipe box 7. One end of each of the two braided water pipes 12 is wound around the water pipe winding shaft 17. When the water pipe winding shaft 17 rotates, it can wind or unwind the braided water pipes 12. A winding motor 18 connected to the water pipe winding shaft 17 is fixedly installed inside the water pipe box 7. The winding motor 18 is connected to a power supply and a controller. When the winding motor 18 rotates, it can drive the water pipe winding shaft 17 to rotate. When it is necessary to clean the inside of the drain pipe 3, the winding motor 18 and the pull wire motor 16 are started simultaneously. The winding motor 18 drives the water pipe winding shaft 17 to rotate and wind the two braided water pipes 12. 2. The two braided water pipes 12 drive the two circular cleaning plates to move towards the bottom of the two drain pipes 3. At the same time, the pull wire motor 16 starts, drives the two pull wire shafts 14 to rotate and release the two pull wires 11. Conversely, when the pull wire motor 16 drives the two pull wire shafts 14 to rotate and wind the two pull wires 11, it can drive the two circular cleaning plates to move towards the top of the two drain pipes 3. At the same time, the winding motor 18 drives the water pipe winding shaft 17 to rotate and release the two braided water pipes 12. A water pump 19 is installed in the water pipe box 7. Both of the two braided water pipes 12 are connected to the water pump 19. The water pump 19 can provide power to the two braided water pipes 12, so that the spray hole 13 can perform high-pressure flushing on the inner wall of the drain pipe 3.

[0027] In Example 4, based on Example 1, the rotating device includes a rotating bevel gear 20 coaxially mounted inside the drain pipe 3 and coaxially surrounding the outside of the braided water pipe 12. The rotating bevel gear 20 is located below the sealing plate 04. Two limiting wheels 21 located on both sides of the braided water pipe 12 are rotatably mounted on the inner side of the rotating bevel gear 20. The axes of the two limiting wheels 21 are perpendicular to the axis of the rotating bevel gear 20. The two limiting wheels 21 can rotate on the inner side of the rotating bevel gear 20, and when the rotating bevel gear 20 rotates, it can drive the two limiting wheels 21 to rotate. Spikes 22 are fixedly mounted on the outer surface of the two limiting wheels 21. When the braided water pipe 12 passes through the middle of the rotating bevel gear 20, the spikes 22 on the two limiting wheels 21 can pierce the braided layer on the outside of the braided water pipe 12. When the water pipe winding shaft 17 winds around the braided water pipe 12, the braided water pipe 12... The axial movement of the central part of the rotating bevel gear 20 and the axial movement of the braided water pipe 12 can drive the two limiting wheels 21 to rotate. When the rotating bevel gear 20 rotates, the protrusions 22 on the outer side of the two limiting wheels 21 penetrate the braided layer of the braided water pipe 12. Therefore, when the rotating bevel gear 20 rotates, it can drive the braided water pipe 12 to rotate through the protrusions 22, thereby causing the sealing rod 101 to rotate and the two fan-shaped sealing plates 102 to rotate circumferentially, thus forming a circular cleaning plate with the two fan-shaped cleaning plates 902. The inner side of the drain pipe 3 is rotatably mounted with a drive bevel gear 23 that meshes with the rotating bevel gear 20. The outer side of the drain pipe 3 is fixedly mounted with a rotary motor 24 connected to the drive bevel gear 23. The rotary motor 24 is connected to a power supply and a controller. When the rotary motor 24 is started, it drives the drive bevel gear 23 to rotate, and the drive bevel gear 23 can drive the rotating bevel gear 20 to rotate.

[0028] In Example 5, based on Example 4, each of the two fan-shaped cleaning plates 902 has an arc-shaped limiting groove 25 on the side away from the pull box 2. Each of the two fan-shaped sealing plates 102 has a limiting block 26 fixedly installed in the arc-shaped limiting groove 25 on the side near the pull box 2. Through the sliding cooperation between the limiting block 26 and the arc-shaped limiting groove 25, the two fan-shaped sealing plates 102 move along the arc-shaped limiting groove 25. When the limiting block 26 moves from one end of the arc-shaped limiting groove 25 to the other end, the two fan-shaped sealing plates 102 will form a circular sealing plate with the two fan-shaped cleaning plates 902.

[0029] In Example 6, based on Example 4, the braided water pipe 12 is a stainless steel braided water pipe with an outer layer of stainless steel wire braid. The stainless steel wire braid increases the durability of the braided water pipe 12, and when the rotating bevel gear 20 drives it to rotate, it is not easy for it to undergo axial torsion, ensuring the normal flow of water inside, and it can also be properly wound on the water pipe winding shaft 17.

[0030] A method for using a drainage and waterproofing device for high-pressure water tunnels, characterized in that the method of use is as follows: a. During drainage: groundwater outside the tunnel lining 01 flows into the drainage channel 4, and through the drainage pipe 5 into the drainage pipe 3, and is discharged from the outlet pipe 03 into the drainage ditch 02; b. During cleaning: First, the rotating motor 24 drives the rotating helical gear 20 to rotate. The rotating helical gear drives the braided water pipe 12 to rotate through two limiting wheels 21 with spikes 22. The braided water pipe 12 drives the sealing rod 101 to rotate. The sealing rod 101 drives the two fan-shaped sealing plates 10 to move circumferentially to the space between the two fan-shaped cleaning plates 902, so that the two fan-shaped cleaning plates 902 and the two fan-shaped sealing plates 101 form a complete circular cleaning plate that is sealed and fits tightly against the inner wall of the drain pipe 3. c. Then, start the wire pulling motor 16 and the winding motor 18 at the same time. The winding motor 18 starts and drives the water pipe winding shaft 17 to rotate and starts to wind the two braided water pipes 12. When the braided water pipes 12 pass through the rotating helical gear 20 in the axial direction, they can drive the two limiting wheels 21 to rotate. At the same time, the wire pulling motor 16 starts and drives the two wire pulling shafts 14 to release the two wires 11. The two braided water pipes 12 can pull the two circular cleaning plates to move along the drain pipe 3, thereby scraping off the mud and sand on the inner wall of the drain pipe 3 for cleaning. At the same time, the braided water pipes 12 are supplied with water by the water pump 19 and clean the inner wall of the drain pipe 13 through the spray hole 13. d. Upon completion of cleaning: First, start the rotary motor 24 in reverse, causing the braided water pipe 12 and the sealing rod 101 to rotate in the opposite direction. The two sector-shaped sealing plates 102 rotate in the opposite direction to return to the state of overlapping with the two sector-shaped cleaning plates. Then, start the pull motor 16 and the winding motor 18 in reverse at the same time, causing the two pull shafts 14 to rotate and wind the two pull wires 11, while the water pipe winding shaft 17 releases the two braided water pipes 12. As the two pull wires 11 are gradually wound, they can pull the top of the two cleaning rods 901 and the drain pipe 3 to move and reset.

7. A method for using the waterproof and drainage device of the high-pressure water tunnel, which is applied to the device described in claim 4, characterized in that, Its usage method is as follows: a. During drainage: groundwater outside the tunnel lining (01) flows into the drainage channel (4), and through the drainage pipe (5) into the drainage pipe (3), and is discharged from the outlet pipe (03) into the drainage ditch (02); b. During cleaning: First, the rotating helical gear (20) is driven to rotate by the rotating motor (24). The rotating helical gear drives the braided water pipe (12) to rotate through the two limiting wheels (21) with spikes (22). The braided water pipe (12) drives the sealing rod (101) to rotate. The sealing rod (101) drives the two fan-shaped sealing plates (10) to move circumferentially to the space between the two fan-shaped cleaning plates (902), so that the two fan-shaped cleaning plates (902) and the two fan-shaped sealing plates (101) form a complete circular cleaning plate that is sealed and fits tightly against the inner wall of the drain pipe (3). c. Then, start the wire pulling motor (16) and the winding motor (18) at the same time. The winding motor (18) starts and drives the water pipe winding shaft (17) to rotate and starts to wind two braided water pipes (12). When the braided water pipe 12 passes through the rotating helical gear 20 in the axial direction, it can drive the two limiting wheels 21 to rotate. At the same time, the wire pulling motor (16) starts and drives the two wire pulling shafts (14) to release the two wires (11). The two braided water pipes (12) can pull the two circular cleaning plates to move along the drain pipe (3), so as to scrape off the mud and sand on the inner wall of the drain pipe (3) for cleaning. At the same time, the braided water pipe (12) supplies water through the water pump (19) and cleans the inner wall of the drain pipe (13) through the spray hole (13). d. When cleaning is completed: First, start the rotary motor (24) in reverse so that the braided water pipe (12) and sealing rod (101) rotate in the opposite direction and the two fan-shaped sealing plates (102) rotate in the opposite direction to return to the state of overlapping with the two fan-shaped cleaning plates. Then, start the pull wire motor (16) and winding motor (18) in reverse at the same time so that the two pull wire shafts (14) rotate and wind the two pull wires (11), while the water pipe winding shaft (17) releases the two braided water pipes (12). When the two pull wires (11) are gradually wound, they can pull the top of the two cleaning rods (901) and the drain pipe (3) of the box to move and reset.
